Miss Marilyn and Mistress Inka are training their slave JJ to become a cock whore and start being of use to them. They start by examining and teasing, letting him know what is in for store and how he should be behaving, bringing him to his knees, at eye level to their two massive strapon dicks, which they are soon plunging into his open mouth. They humiliate and test his deep throat ability as the big cocks work there way in, noting how hard his cock is getting at the rough use. The new slut is then put on the bondage bench and the Mistresses take turns to finger and stretch his hole with their gloved hands, enjoying the moans of pleasure that are emanating. Once prepared, his tight ass is penetrated, the giant strapons slowly entering, rubbing against his prostate, causing his cock to leak copious precum as they spitroast the lucky sub, in amazing pegging action. They are so pleased with his progress they decide to bring in another thick cocked slave, who is directed to fuck the new slut, taken his first ever real dick, the Mistresses guiding and encouraging the action until he shoots a big load into JJ’s eager face, the slut whore transformation fully completed, much to their delight.
